The wavy composite core includes wavy filtering layers and flat filtering layers alternately stacked and rolled to form a barrel shape for filtering suspended pollutants. Each wavy filtering layer has a plurality of peak portions extending axially, a plurality of axial sealing adhesive layers formed on the peak portions by coating sealing adhesive on the peak portions so as to bond the wavy filtering layer to the flat filtering layers adjacent to the wavy filtering layer, and two end sealing adhesive layers formed on opposite sides by coating sealing adhesive on the wavy filtering layer to bond the wavy filtering layer to the adjacent flat filtering layers. ## Claims ### Claim 1 A wavy composite core comprising a plurality of wavy filtering layers and a plurality of flat filtering layers alternately stacked and rolled to form a barrel for filtering suspended pollutants, wherein each wavy filtering layer has a plurality of peak portions extending axially, a plurality of axial sealing adhesive layers formed on the peak portions by coating sealing adhesive on the peak portions so as to bond the wavy filtering layer to the flat filtering layers adjacent to the wavy filtering layer, and two end sealing adhesive layers formed on opposite ends of the wavy filtering layer by coating sealing adhesive on the wavy filtering layer to bond the wavy filtering layer to the adjacent flat filtering layers. ### Claim 2 (depends on 1) The wavy composite core as claimed in claim 1, wherein each wavy filtering layer has a first side, a second side, a first end and a second end opposite the first end, one of the end sealing adhesive layers is formed on the first side at the first end, and the other end sealing adhesive layer is formed on the second side and at the second end. ### Claim 3 (depends on 1) The wavy composite core as claimed in claim 1, wherein each wavy filtering layer has a first side, a second side, a first end and a second end opposite the first end, one of the end sealing adhesive layers is formed on the second side at the first end, and the other end sealing adhesive layer is formed on the first side and at the second end. ### Claim 4 A manufacturing method for a wavy composite core, comprising the following steps: (a) forming a wavy filtering layer and a flat filtering layer for filtering suspended pollutants, wherein raw material is pressed by shaping rollers to form the wavy filtering layer having peak portions on which axial sealing adhesive layers are formed by coating sealing adhesive on the peak portions, and the raw material is tensioned by a driving roller and a press roller to form the flat filtering layer at the same time; (b) forming a first end sealing adhesive layer and bonding the wavy filtering layer to the flat filtering layer, wherein the first end sealing adhesive layer is formed on the wavy filtering layer by coating sealing adhesive at one end on one side of the wavy filtering layer by a first gluing gun, and the flat filtering layer is pressed and bonded to the wavy filtering layer by means of the axial sealing adhesive layers and the first end sealing adhesive layer; (c) forming a second end sealing adhesive layer, wherein the second end sealing adhesive layer is formed on the wavy filtering layer by coating sealing adhesive at the other end on the other side of the wavy filtering layer by a second gluing gun; and (d) obtaining the wavy composite core material, wherein the bonded wavy filtering layer and flat filtering layer are rolled to form the wavy composite core having a barrel shape. ### Claim 5 (depends on 4) The manufacturing method as claimed in claim 4, wherein in the step (a), raw material is conveyed through a lower shaping roller to be preheated and through an upper shaping roller to form a wavy shape. ### Claim 6 (depends on 5) The manufacturing method as claimed in claim 5, wherein in the step (b), the press roller conveys and cools the bonded wavy filtering layer and flat filtering layer. ### Claim 7 (depends on 6) The manufacturing method as claimed in claim 6, wherein in the step (c), the bonded wavy filtering layer and flat filtering layer are conveyed by an annular driving roller to engage with a toothed roller and moved by the toothed roller to the second gluing gun. ### Claim 8 (depends on 7) The manufacturing method as claimed in claim 7, wherein in the step (a), the sealing adhesive is coated on the peak portions by a gluing roller. ### Claim 9 (depends on 5) The manufacturing method as claimed in claim 5, wherein in the step (c), the bonded wavy filtering layer and flat filtering layer are conveyed by an annular driving roller to engage with a toothed roller and moved by the toothed roller to the second gluing gun. ### Claim 10 (depends on 5) The manufacturing method as claimed in claim 5, wherein in the step (a), the sealing adhesive is coated on the peak portions by a gluing roller. ### Claim 11 (depends on 4) The manufacturing method as claimed in claim 4, wherein in the step (b), the press roller conveys and cools the bonded wavy filtering layer and flat filtering layer. ### Claim 12 (depends on 11) The manufacturing method as claimed in claim 11, wherein in the step (c), the bonded wavy filtering layer and flat filtering layer are conveyed by an annular driving roller to engage with a toothed roller and moved by the toothed roller to the second gluing gun. ### Claim 13 (depends on 12) The manufacturing method as claimed in claim 12, wherein in the step (a), the sealing adhesive is coated on the peak portions by a gluing roller. ### Claim 14 (depends on 4) The manufacturing method as claimed in claim 4, wherein in the step (c), the bonded wavy filtering layer and flat filtering layer is conveyed by an annular driving roller to engage with a toothed roller and moved by the toothed roller to the second gluing gun. ### Claim 15 (depends on 4) The manufacturing method as claimed in claim 4, wherein in the step (a), the sealing adhesive are coated on the peak portions by a gluing roller.
